Abstract/ Executive Summary:

The performance of two persimmon accession was studied at the HRC, BARI, Gazipur during 2013-14. The growth of both the germplasm was satisfactory. The tallest plant (5.0 m) with maximum branches/plant (5.0) was found in DK Joy-002. The floral bud emerged with new vegetative flush in both accessions on early March. The DK Joy-001 flowered once in early April and another in mid December but DK Joy-002 flowered once in mid April. Heaviest fruit (72 g) with maximum length and diameter (4.30 and 5.00 cm, respectively) was recorded from DK Joy-001, while it was noted minimum (60 g, 4.80 and 4.60 cm, respectively) in DK Joy-002. Maximum number of fruits and yield/plant (280 and 17 kg, respectively) was harvested from DK Joy-002, while that of minimum (78 and 8.0 kg) in DK Joy-001. The skin and seed weight/fruit was obtained 7.5 and 1.40 g, respectively in DK Joy-002 and 7.0 and 1.50 g, respectively in DK Joy-001. Maximum TSS (15.0) was recorded in DK Joy-001 compared to minimum (13.0) in DK Joy-002. Edible portion was noted 85% with Globose shaped fruit having deep orange and very soft pulp, flat shaped and brown coloured seed having in both the germplasm.

Objectives:

To study the performance of promising persimmon genotypes in Bangladesh

Evaluate, characterized and documented the collected persimmon germplasm for introducing in Bangladesh

To select a superior persimmon line having higher yield and good quality for release as a variety.

Methodology:

The study was conducted with two persimmon germplasm namely DK Joy-001 and DK Joy-002 during 2013-2014 at Horticulture Research Centre, BARI, Gazipur. Some grafts of DK Joy-001 were collected from Japan at 1980 and planted in nursery of HRC, BARI. Another germplasm (DK Joy-002) was collected by Honorable Agriculture Minister of Bangladesh and panted at Fruit Research Farm, BARI, Joydebpur, Gazipur in 1996. The plants were fertilized with cow dung (20 kg), urea (250 g), TSP (250 g) and MoP (150 g) in two equal installments one is before onset of rainy season and another one is after rainy season. Besides this dose of fertilizer, the plants were fed with 200 g urea, 250 g TSP, 200 g MoP and 100 g boric acid at mid April 2014 for proper fruit growth. Light irrigation was given after fertilization in each installment. Irrigation was given at 15 days interval in the dry period (October to February). Dead and undesired branches were pruned after harvest of fruit in August. Ripcord 25 EC (Cypermethrion) was sprayed at the time of new vegetative flashing (February – March) to control the chaffer beetle infestation. Data on plant height (m), base girth (cm), plant spreading on N-S and E-W direction (m), growth condition of plants, branching density, time of blooming, time of harvesting, number of fruits/plant, fruit weight (g), fruit length (cm), fruit breadth (cm), number of seed/fruit, seed weight (g), seed length (cm), seed breadth (cm), skin weight (g), yield/plant (kg), TSS (%), edible portion (%), fruit shape, skin color, flesh colour, seed colour, seed shape, and organoleptic taste were recorded as per IPGRI descriptors. The date were analyzed by Microsoft excel programme for interpretation the results properly.

1. Government

Budget: 17000/-

Total Budget (Tk.) : 17000/-

Achievement/Findings:

Growth of both the germplasm was satisfactory. Maximum fruits per plant along with yield/plant and TSS were recorded in DK Joy-002 on the other hand single fruit weight, fruit size and two time bearing in a year make both the germplasm promising for cultivation in Bangladesh.
